Abstract
A video encoding/decoding system includes a video encoding device and a video decoding device. The video encoding device includes an encoding part for encoding a diagnostic image or normal image. The video decoding device includes a decoding part for decoding the image encoded by the encoding part, a check signal generation part for generating a check signal of the decoded image, a storage part for storing the expected value of the check signal of the diagnostic image or the check signal generated by the check signal generation part, and a comparison part for comparing the check signal stored in the storage part with the check signal generated by the check signal generation part, in order to detect failure in all the paths from the image input part of the video encoding device to the image output part of the video decoding device.
